Summary: Review planning guidance for Office Web Apps when it is used with SharePoint 2013 on-premises.
Audience: IT Professionals
To plan how Office Web Apps is used with SharePoint 2013 on-premises, you should review browser support, SharePoint authentication requirements, and licensing considerations for viewing and editing Office files by using Office Web Apps. Then, you can decide whether you want SharePoint 2013 to use the web browser or a client application when a user opens Office files from a SharePoint 2013 document library.

The guidance in this article is a subset of the overall planning you’ll do when you deploy Office Web Apps Server on-premises in your organization. For example, hardware, software, and virtualization requirements, farm sizing and topology, and security are all part of Office Web Apps Server planning. After you make those decisions, you can plan how to configure Office Web Apps functionality that is specific to SharePoint 2013. If you haven’t heard of Office Web Apps Server or reviewed its requirements and planning guidance, see Office Web Apps Server overview and Plan Office Web Apps Server.
Browser support for Office Web Apps is the same as for SharePoint 2013. Refer to the article Plan browser support in SharePoint 2013 for more information.
Office Web Apps can be used only by SharePoint 2013 web applications that use claims-based authentication. Office Web Apps rendering and editing will not work on SharePoint 2013 web applications that use classic mode authentication. If you migrate SharePoint 2010 web applications that use classic mode authentication to SharePoint 2013, you must migrate them to claims-based authentication to allow them to work with Office Web Apps. To learn more, see Migrate from classic-mode to claims-based authentication in SharePoint 2013.
Office Web Apps licensing offers two options:
View-only. By default, Office Web Apps is view-only. View-only functionality is provided for free.
Edit and view. You must purchase an editing license to use the editing features of Office Web Apps with SharePoint 2013. You enable editing when you create the Office Web Apps Server farm.
Enterprise customers who are licensed for Office 2013 through a Volume Licensing program can enable Office Web Apps editing for SharePoint 2013 on-premises. This helps make sure that users have Office editing capabilities at home or in other locations where Office clients might not be installed. Editing licenses for Office Web Apps are not available for separate purchase.
For exact details about your license, refer to the Microsoft Software License Terms that is shown when you install Office Web Apps Server.
SharePoint 2013 provides new license enforcement that works with Office Web Apps. If you enable SharePoint licensing and then enable Office Web Apps editing, only the users who have the appropriate license, which is known as OfficeWebAppsEdit, can actually edit Office files in a browser. If no Office Web Apps editing licenses are applied for users, only viewing is supported. For more information about how licensing works in SharePoint 2013, see Configure licensing in SharePoint Server 2013. The EditingEnabled parameter that enables editing is described in New-OfficeWebAppsFarm and Set-OfficeWebAppsFarm.
If you installed Office Web Apps together with SharePoint 2010, Office Web Apps will not be available after you upgrade to SharePoint 2013. You must deploy Office Web Apps Server and then connect SharePoint 2013 to it after the content databases are upgraded. You don't have to wait until the site collections are upgraded because Office Web Apps Server supports both the 2010 and 2013 site collection modes in SharePoint 2013. For more information about the database attach method, see Overview of the upgrade process to SharePoint 2013.
You can configure whether Word, PowerPoint, Excel, and OneNote files are opened in a client application (if it is installed) or in the browser. By default, after SharePoint 2013 is configured to use Office Web Apps Server, Office files are opened in the browser. There are two ways to change the default behavior to allow client applications to open files directly:
For the SharePoint 2013 farm You can adjust the default open behavior on a per-file-type basis for the SharePoint 2013 farm by using the New-SPWOPIBinding and Set-SPWOPIBinding Windows PowerShell cmdlets.
On site collections or document libraries Site collection administrators and users can specify whether Office files are opened in the client applications if it is installed. Users can change this setting in the document library properties, and site collection administrators can change this setting in Site Collection Administration or by using the Install-SPFeature cmdlet to install the OpenInClient feature. For more information, see Install-SPFeature.
